Hi! When you edit the base solid, you are in a special non-parametric environment. Only limited functionality (local geometric operation like Move Face, Offset, and Expand/Contract) is available there. You might notice that there are no dimensions or parameters there. And, there are not associative features.
If you want to create Work features or any other parametric features, you will need to finish editing base solid and return to parametric enviornment.
